Abstract

The discharger for a bin (3) carried on a truck or trailer comprises a telescopic hydraulic power cylinder at the front end of the bin that moves a pusher towards the open rear end to discharge the bin's contents. The periphery of the pusher is shaped to match the cross-section of the bin, and its contact surface is concave and curved. The pusher has a deflector at the top and a seal between its periphery and the bin surface, and is guided by rollers running in guide rails (111) on the inside or outside of the bin's upper edges.

Description

La présente invention se rapporte au domaine technique des poussoirs d'éjection actionnés par un vérin horizontal et destinés à équiper des bennes à éjection horizontale. Elle vise également lesdites bennes à éjection horizontale, équipées de tel poussoirs. Elle vise encore des remorques, semi-remorques, et véhicules porteurs équipés de telles bennes.The present invention relates to the technical field of pushers ejection actuated by a horizontal cylinder and intended to equip skips with horizontal ejection. It also relates to said ejection skips horizontal, fitted with such pushers. She’s still targeting trailers, semi-trailers, and carrier vehicles fitted with such skips.

Dans le transport dans des bennes de matériaux en vrac, comme par exemple de l'asphalte ou des blocs de pierre, ou encore des céréales, on a depuis longtemps utilisé des dispositifs permettant un déchargement de la benne dit « par gravité » des matériaux, c'est à dire par élévation progressive de l'avant de la benne au moyen d'un vérin ou autre élévateur.In the transport in bins of bulk materials, such as by example of asphalt or stone blocks, or even cereals, we have long used devices for discharging the bucket says "by gravity" of the materials, ie by elevation progressive from the front of the bucket by means of a jack or other elevator.

On a ensuite utilisé des dispositifs permettant le déchargement horizontal de la benne, c'est à dire que le matériau contenu dans la benne est poussé vers l'arrière au moyen d'un dispositif poussoir actionné par un vérin horizontal, le vérin étant disposé entre le dispositif poussoir et l'avant de la benne. L'évacuation des matériaux se fait par l'arrière de la benne, qui est ouverte ou fermée au moyen d'une porte relevable articulée.We then used devices allowing the horizontal unloading of the bucket, i.e. the material contained in the bucket is pushed towards the rear by means of a pusher device actuated by a horizontal cylinder, the cylinder being disposed between the pusher device and the front of the bucket. The materials are removed from the rear of the bucket, which is open or closed by means of a hinged hinged door.

On connaít déjà des bennes à éjection horizontale munies de poussoirs d'éjection, qui sont fixées sur le châssis d'un véhicule porteur, d'une remorque ou d'une semi-remorque. Pour simplifier, dans la suite de la demande on désignera par « véhicule » un véhicule porteur motorisé, une remorque ou une semi-remorque.We already know skips with horizontal ejection provided with pushers ejection, which are fixed to the chassis of a carrier vehicle, of a trailer or a semi-trailer. To simplify, in the rest of the request we will designate by “vehicle” a motorized carrier vehicle, a trailer or a semi-trailer.

D'une manière générale, le poussoir se déplace à l'intérieur de la benne le long de sa direction longitudinale, de l'avant vers l'arrière de la benne pour l'opération de déchargement, et de l'arrière vers l'avant pour le retour du poussoir en position rétractée. Le poussoir est guidé au cours de son déplacement par des moyens de guidage, disposés sur le poussoir et/ou sur la benne.Generally, the pusher moves inside the bucket the along its longitudinal direction, from the front to the rear of the bucket to the unloading operation, and from back to front for the return of the pusher in retracted position. The pusher is guided during its displacement by guide means, arranged on the pusher and / or on the bucket.

Les poussoirs et bennes de l'art antérieur présentent des inconvénients importants. Avec les dispositifs de déchargement de l'art antérieur, on rencontre régulièrement des difficultés lors du déchargement de certains matériaux, notamment des terres argileuses, des matériaux concassés, qui ont tendance à se compacter pendant leur transport et à adhérer fortement aux parois de la benne lors du déchargement. Un tel comportement des matériaux a pour conséquence que les efforts exercés sur les poussoirs et bennes de l'art antérieur sont très importants. Ces efforts entraínent régulièrement des déformations de la benne, telles que vrillage ou flambage, ainsi que l'endommagement du joint d'étanchéité du poussoir. Les réparations nécessitent des périodes d'immobilisation du véhicule, qui engendrent des surcoûts d'exploitation.The pushers and skips of the prior art have drawbacks important. With the unloading devices of the prior art, we regularly encounter difficulties when unloading some materials, including clay soils, crushed materials, which tend to compact during transport and strongly adhere to the sides of the bucket during unloading. Such behavior of materials has the consequence that the forces exerted on the pushers and skips of the prior art are very important. These efforts lead to regular deformations of the bucket, such as twisting or buckling, as well as damage to the pusher seal. The repairs require periods of immobilization of the vehicle, which generate additional operating costs.

L'invention a pour objet de proposer un dispositif de déchargement: poussoir d'éjection, benne, véhicule, qui ne présente pas les inconvénients des dispositifs de l'art antérieur, qui soit d'une fabrication simple et d'un coût réduit.The object of the invention is to propose an unloading device: ejection button, bucket, vehicle, which does not have the drawbacks devices of the prior art, which is simple to manufacture and cost reduced.

Selon encore un autre aspect de l'invention, le véhicule est caractérisé en ce qu'il est équipé d'une benne conforme à l'invention.

Elle est ouverte en partie supérieure et présente une section transversale cintrée 5 en forme de demi-cercle qui se prolonge de part et d'autre vers le haut par un bord rectiligne vertical supérieur 7. Selon une variante non illustrée, la section transversale cintrée 5 est en forme de demi-ovale, cette forme étant plus adaptée au transport des céréales. La paroi de la benne 3 peut être une paroi simple, ou bien une paroi double lorsque les matériaux transportés exercent des efforts de nature à déformer ladite paroi.The bucket 3 is shown in rear view in FIG. 2. It is open at upper part and has a curved cross section 5 in the form of semicircle which extends on both sides upwards by an edge upper vertical rectilinear 7. According to a variant not illustrated, the section curved transverse 5 is in the shape of a half-oval, this shape being more suitable for grain transportation. The wall of the bucket 3 can be a single wall, or a double wall when the materials transported exert efforts to deform said wall.

La benne 3 comprend des premiers moyens longitudinaux de rigidification 11 et des seconds moyens longitudinaux de rigidification 13, illustrés aux figures 1 à 6.The bucket 3 comprises first longitudinal stiffening means 11 and second longitudinal stiffening means 13, illustrated in Figures 1 to 6.

Les premiers moyens longitudinaux de rigidification 11 ont pour fonction d'empêcher les déformations en partie supérieure de la benne 3. Ils comprennent deux profilés longitudinaux supérieurs et extérieurs 11, fixés respectivement sur la face extérieure de chaque bord supérieur 7 de la benne 3.The first longitudinal stiffening means 11 have the function prevent deformation in the upper part of the bucket 3. They include two upper and outer longitudinal sections 11, fixed respectively on the outer face of each upper edge 7 of the bucket 3.

Les seconds moyens longitudinaux de rigidification 13 comprennent deux profilés longitudinaux intermédiaires 13 disposés entre le fond de la benne 3 et chaque bord supérieur 7 de la benne 3, sur la face extérieure de celle-ci. Ces profilés 13 sont de préférence pliés en forme de U. Ces seconds moyens longitudinaux de rigidification 13 ont pour fonction d'empêcher les déformations en partie cintrée de la benne 3 et le vrillage des parois de la benne 3, ce qui réduit considérablement les jeux entre le poussoir 51 et les parois de la benne 3 lors du déplacement du poussoir 51.The second longitudinal stiffening means 13 comprise two intermediate longitudinal sections 13 disposed between the bottom of the bucket 3 and each upper edge 7 of the bucket 3, on the outer face of the latter. These sections 13 are preferably folded into a U shape. These second longitudinal stiffening means 13 have the function of preventing partially curved deformations of the bucket 3 and the twisting of the walls of the bucket 3, which considerably reduces the clearance between the pusher 51 and the walls of the bucket 3 during movement of the pusher 51.

En partie avant supérieure de la benne 3 est prévu un capot 15, illustré à la figure 1, qui présente une face extérieure convexe bombée en portion de sphère. Le capot 15 a pour fonction de maintenir l'écartement entre les deux profilés supérieurs 11 et les deux profilés intermédiaires 13. Sa forme présente également l'avantage d'offrir une moindre prise au vent lors des trajets.In the upper front part of the bucket 3 is provided a cover 15, illustrated in the Figure 1, which has a convex outer face curved in portion of sphere. The cover 15 has the function of maintaining the spacing between the two upper sections 11 and the two intermediate sections 13. Its shape also has the advantage of offering less wind resistance during trips.

En partie arrière de la benne 3 est articulée une porte relevable 17, illustrée à la figure 1, dont l'ouverture et la fermeture sont actionnées par deux vérins hydrauliques latéraux 19 orientés selon une direction sensiblement verticale. Selon une variante avantageuse, la porte 17 est en outre équipée de détecteurs de présence par contact, par induction ou par rayons laser. Ces détecteurs, non représentés aux figures, permettent d'éviter une fausse manoeuvre de la commande hydraulique, et d'éviter une éjection intempestive des matériaux lorsque la porte n'est pas ouverte, ce qui aurait sinon pour conséquence d'endommager la porte 17 ou de provoquer un accident corporel d'une personne située à proximité de la benne 3. Ils permettent également d'éviter que la porte 17 soit refermée avant que le poussoir 51 ne soit retourné en position rétractée vers l'avant de la benne 3, ce qui aurait sinon pour conséquence d'endommager le joint d'étanchéité 55 ou le vérin 81 dudit poussoir 51.In the rear part of the bucket 3 is hinged a lifting door 17, illustrated in Figure 1, the opening and closing are actuated by two cylinders lateral hydraulics 19 oriented in a substantially vertical direction. According to an advantageous variant, the door 17 is further equipped with presence detectors by contact, induction or laser beams. These detectors, not shown in the figures, make it possible to avoid a false operation of the hydraulic control, and to avoid ejection untimely materials when the door is not open, which would have otherwise, as a result of damaging door 17 or causing a bodily accident of a person located near the skip 3. They also prevent door 17 from being closed before the pusher 51 has not returned to the retracted position towards the front of the bucket 3, which would otherwise damage the seal 55 or the jack 81 of said pusher 51.

Toujours en partie arrière de la benne 3 est disposé un anneau de rigidification 21. Il a pour fonction d'empêcher les déformations à l'arrière de la benne 3 et peut en outre recevoir des moyens de fixation et d'articulation de la porte relevable 17. Il présente également deux logements latéraux 23 pour abriter les vérins latéraux 19 d'actionnement de ladite porte 17.Still in the rear part of the bucket 3 is arranged a ring of stiffening 21. Its function is to prevent deformation at the rear of the bucket 3 and can also receive fixing and articulation means for the lift door 17. It also has two lateral housings 23 to house the lateral actuators 19 for actuating said door 17.

De façon préférée lorsque la benne 3 présente des dimensions importantes en longueur et/ou en hauteur, un ou plusieurs anneaux supplémentaires de rigidification (non représentés) peuvent être prévus entre l'avant et l'arrière de la benne 3. Ils ont pour fonction de rigidifier les parois latérales de la benne 3, et d'empêcher le flambage de la benne 3 en partie supérieure.Preferably when the bucket 3 has large dimensions in length and / or height, one or more additional rings of stiffening (not shown) may be provided between the front and the rear of the bucket 3. Their function is to stiffen the side walls of the bucket 3, and to prevent buckling of the bucket 3 in the upper part.

Les figures 1 et 2 illustrent plus particulièrement le cas où le véhicule est une semi-remorque. Celle-ci comprend un châssis 25 qui repose sur le sol 27 (figure 1) au moyen de roues 29 montées sur des ensembles essieux/suspensions 31, de préférence au nombre de deux ou trois et de béquilles 33, de préférence au nombre de deux. Ledit châssis 25 comprend deux longerons longitudinaux 35 sur les extrémités arrière desquels sont fixés les ensembles essieux/suspensions 31. Des traverses de renfort 37, de préférence au nombre de cinq à sept, sont fixées entre lesdits longerons 35, notamment au niveau des ensembles essieux/suspensions 31 et au niveau des béquilles 33. Une traverse supplémentaire 39 en forme de U est prévue vers l'avant du châssis 25, pour l'installation d'une cheville ouvrière démontable 41.Figures 1 and 2 illustrate more particularly the case where the vehicle is a semi-trailer. This includes a frame 25 which rests on the ground 27 (Figure 1) by means of wheels 29 mounted on assemblies axles / suspensions 31, preferably two or three in number and crutches 33, preferably two in number. Said chassis 25 includes two longitudinal beams 35 on the rear ends of which are fixed the axle / suspension assemblies 31. Reinforcement crosspieces 37, preferably five to seven in number, are fixed between said beams 35, in particular at the level of the axle / suspension assemblies 31 and at level of crutches 33. An additional U-shaped cross member 39 is provided towards the front of chassis 25, for the installation of a kingpin removable 41.

La fixation de la benne au châssis 25 du véhicule (voir figure 1) est réalisée de préférence par soudage ou boulonnage du soubassement de la benne 3 sur ledit châssis 25.The bucket is fixed to the chassis 25 of the vehicle (see Figure 1). preferably by welding or bolting the body of the bucket 3 on said chassis 25.

Selon une variante avantageuse, les longerons 35 du châssis 25 présentent une inclinaison de 4 à 6 % par rapport à l'horizontale, la partie la plus basse se trouvant à l'arrière du véhicule. Cette inclinaison a pour avantage de favoriser le déchargement vers l'arrière et d'abaisser le centre de gravité de la semi-remorque.According to an advantageous variant, the longitudinal members 35 of the chassis 25 have an inclination of 4 to 6% from the horizontal, the lowest part located at the rear of the vehicle. This inclination has the advantage of favor unloading backwards and lower the center of gravity of the semi-trailer.

Selon une variante avantageuse représentée à la figure 4 et destinée à équiper tous types de véhicules, un faux châssis 45 est disposé sous le soubassement de la benne 3. Ce faux châssis 45 comprend deux longerons 451 et des traverses 453 servant d'entretoises entre lesdits longerons 451. Le faux châssis 45 remplit une fonction de renfort du soubassement de la benne 3. Il est adapté pour plaquer parfaitement au soubassement de la benne 3, ce qui permet une fixation sans déformation, du soubassement de la benne 3 au châssis 25 par l'intermédiaire du faux châssis 45.According to an advantageous variant represented in FIG. 4 and intended for equip all types of vehicles, a false chassis 45 is placed under the underbody of the bucket 3. This false chassis 45 comprises two beams 451 and crosspieces 453 serving as spacers between said longitudinal members 451. The false chassis 45 fulfills a function of reinforcing the underbody of the bucket 3. It is suitable for flattening perfectly underbody of the bucket 3, which allows fixing without deformation, from the base of the bucket 3 to the chassis 25 via the dummy chassis 45.

Les moyens de fixation 47, 49 du faux châssis 45 sur le châssis 25 du véhicule comprennent de préférence le soudage, le boulonnage ou le verrouillage mécanique ou hydraulique. Le châssis 25 peut être indifféremment un châssis de semi-remorque à deux ou trois essieux, ou un châssis de remorque à deux ou trois essieux, ou un châssis de véhicule porteur motorisé.The fixing means 47, 49 of the false chassis 45 on the chassis 25 of the vehicle preferably include welding, bolting or mechanical or hydraulic locking. The frame 25 can be either a two- or three-axle semi-trailer chassis, or a two- or three-axle trailer chassis, or a vehicle chassis motorized carrier.

Un avantage de la benne 3 équipée d'un faux châssis 45 est qu'elle peut être installée sur tous types de châssis 25 de remorques, de semi-remorques ou de véhicules porteurs motorisés qui sont par ailleurs également aptes à recevoir des bennes à déchargement par gravité. Il est donc possible à un utilisateur d'utiliser indifféremment une benne 3 à déchargement horizontal et une benne classique à déchargement par gravité sur un même châssis 25, ce qui réduit considérablement ses coûts d'exploitation.An advantage of the bucket 3 equipped with a false chassis 45 is that it can be installed on all types of chassis 25 for trailers, semi-trailers or motorized carrier vehicles which are otherwise also suitable for receiving gravity unloading skips. It is therefore possible for a user to use a grab 3 to horizontal unloading and a conventional gravity unloading grab on the same chassis 25, which considerably reduces its costs operating.

Le poussoir d'éjection 51 est représenté aux figures 5 et 6, respectivement en coupe latérale et en vue de dessus. Il comprend une face de contact 53 avec les matériaux transportés et/ou éjectés et un déflecteur 55 en partie supérieure. Il est de préférence muni d'un doublage de protection 57.The ejection pusher 51 is shown in FIGS. 5 and 6, respectively in side section and in top view. It includes a contact face 53 with the transported and / or ejected materials and a deflector 55 in part higher. It is preferably provided with a protective lining 57.

La face de contact 53 présente une forme concave, la concavité étant orientée vers le matériau à éjecter, c'est à dire vers l'arrière de la benne 3. Cette forme concave présente l'avantage de faciliter la pénétration du poussoir 51 dans la masse de matériaux à éjecter.The contact face 53 has a concave shape, the concavity being oriented towards the material to be ejected, i.e. towards the rear of the bucket 3. This concave shape has the advantage of facilitating the penetration of the pusher 51 in the mass of materials to be ejected.

Le centre 59 de la face de contact 53 présente un grand rayon de courbure, de préférence de l'ordre de 5 mètres, qui lui confère une légère concavité.The center 59 of the contact face 53 has a large radius of curvature, preferably of the order of 5 meters, which gives it a slight concavity.

La périphérie 61 de la face de contact 53 présente, sur toute sa partie en regard des parois de la benne, un rayon de courbure plus petit, de préférence de l'ordre de 0,7 mètres, qui lui confère une concavité accentuée, et qui prolonge la légère concavité centrale sans discontinuité de la surface. La périphérie de poussoir d'éjection 51 est obtenue par repoussage ou toute méthode analogue. The periphery 61 of the contact face 53 has, over its entire part in look at the sides of the bucket, a smaller radius of curvature, preferably of the order of 0.7 meters, which gives it an accentuated concavity, and which extends the slight central concavity without discontinuity of the surface. The periphery of ejection pusher 51 is obtained by pushing back or any analogous method.

Le bord libre supérieur de la face de contact 53 du poussoir 51 se prolonge vers le haut par le déflecteur 55. Le déflecteur 55 est de préférence fixé par soudage sur la partie supérieure du poussoir 51. Sa face orientée vers l'arrière de la benne 3 qui est susceptible d'entrer en contact avec les matériaux éjectés est concave.The upper free edge of the contact face 53 of the pusher 51 extends upwards by the deflector 55. The deflector 55 is preferably fixed by welding on the upper part of pusher 51. Its side facing the rear of the bucket 3 which is likely to come into contact with the ejected material is concave.

Lors de l'éjection des matériaux, la résistance desdits matériaux provoque une augmentation du dôme de matériaux sur la face de contact 53 du poussoir 51. Le déflecteur 55 a alors pour fonction d'empêcher les débordements éventuels de matériaux par-dessus le poussoir d'éjection 51 et par dessus les bords supérieurs 7 de la benne 3.When materials are ejected, the resistance of said materials causes an increase in the dome of materials on the contact face 53 of the push-button 51. The deflector 55 then has the function of preventing possible material overflows over the ejection pusher 51 and over the upper edges 7 of the bucket 3.

Le doublage de protection 57 du poussoir d'éjection 51 est fixé sur la face de contact 53 du poussoir 51. Il a pour fonction d'absorber les chocs de la face de contact 53 provoqués lors du chargement et/ou du déchargement des matériaux lourds. Il a également pour fonction de protéger la face de contact 53 du poussoir 51 contre les agressions des matériaux abrasifs et/ou corrosifs. Il permet ainsi d'éviter l'endommagement ou la déformation de la structure du poussoir 51.The protective lining 57 of the ejection pusher 51 is fixed on the face 53 of the push button 51. Its function is to absorb the shocks of the contact face 53 caused during loading and / or unloading heavy materials. It also has the function of protecting the face of contact 53 of pusher 51 against attack by abrasive materials and / or corrosive. It thus prevents damage or deformation of the pusher structure 51.

Le poussoir d'éjection 51 comprend également un joint d'étanchéité 65 sur son pourtour en contact avec les parois de la benne 3, ledit joint 65 étant maintenu sur ledit pourtour au moyen d'un support de joint 67. Le support de joint 67 est de préférence réalisé par une palette plane terminale de la périphérie de la face de contact 53.The ejection pusher 51 also includes a seal 65 on its periphery in contact with the walls of the bucket 3, said seal 65 being maintained on said periphery by means of a seal support 67. The support of seal 67 is preferably produced by a terminal flat pallet of the periphery of the contact face 53.

De préférence, la palette présente une dimension de 60 à 80 millimètres dans la direction radiale du bouclier et présente un angle d'attaque 63 compris entre 0 et 25 degrés par rapport aux parois intérieures de la benne.Preferably, the pallet has a dimension of 60 to 80 millimeters in the radial direction of the shield and has an angle of attack 63 included between 0 and 25 degrees from the interior walls of the bucket.

Les formes et/ou dimensions du joint 65 et du support de joint 67 facilitent le décollage des matériaux lors de leur éjection, notamment lorsqu'il s'agit de matériaux ayant un pouvoir d'adhérence important, comme par exemple du bitume. Avec la configuration conforme à l'invention, le joint d'étanchéité 65 résiste aux efforts de poussée sans se retourner. Lesdites formes et/ou dimensions permettent également de garantir une bonne étanchéité entre le poussoir 51 et les parois internes de la benne 3, tout en limitant les frottements du poussoir 61 sur les parois de la benne 3 lors du déplacement avant et/ou arrière du poussoir 51 à l'intérieur de la benne 3. The shapes and / or dimensions of the seal 65 and the seal support 67 facilitate the take-off of materials during their ejection, especially when it comes to materials with a high adhesion power, such as for example bitumen. With the configuration according to the invention, the seal 65 withstands pushing forces without turning over. Said forms and / or dimensions also ensure a good seal between the pusher 51 and the internal walls of the bucket 3, while limiting the friction of the pusher 61 on the walls of the bucket 3 during movement front and / or rear of pusher 51 inside the bucket 3.

De manière connue en soi, le joint d'étanchéité 65 est du type monobloc ou d'une seule pièce, et sa fixation sur le support de joint 67 est réalisée par un boulon.In a manner known per se, the seal 65 is of the one-piece type or in one piece, and its attachment to the seal support 67 is carried out by a bolt.

Selon une variante préférée illustrée à la figure 7, le joint d'étanchéité 65 est du type « joint souple» ou « montage fractionné en écaille». Deux bourrelets amortisseurs 73 sont interposés entre le joint 65 et le support de joint 67. L'ensemble est maintenu au moyen d'un couvre-joint 69 fixé sur le support, de préférence par un boulon 71. L'avantage de cette construction est d'augmenter la souplesse du joint 65, ce qui améliore l'ajustage du joint 65 sur la paroi interne 5, 7 de la benne 3 et maintient l'orientation de l'angle d'attaque 63 du joint 65.According to a preferred variant illustrated in FIG. 7, the seal 65 is "flexible joint" or "split shell assembly" type. Of them shock absorbing beads 73 are interposed between the seal 65 and the support of joint 67. The assembly is held by means of a joint cover 69 fixed to the support, preferably by a bolt 71. The advantage of this construction is to increase the flexibility of the seal 65, which improves the fit of the seal 65 on the internal wall 5, 7 of the bucket 3 and maintains the orientation of the angle 63 of the seal 65.

Selon une variante avantageuse du poussoir d'éjection illustrée à la figure 5, le poussoir 51 est un poussoir articulé, comprenant deux volets latéraux 75 qui s'articulent autour d'un axe 77 de part et d'autre du corps principal. Lors de la phase d'éjection des matériaux, le poussoir articulé 51 se comporte de la même manière qu'un poussoir 51 non articulé. Lors du retour en position rétractée du poussoir 51, les volets latéraux 75 ont la possibilité de se refermer en direction du plan de symétrie verticale de la benne 3, ce qui minimise les frottements du poussoir 51 contre les parois de la benne 3, et favorise ladite rétractation du poussoir 51.According to an advantageous variant of the ejection pusher illustrated in FIG. 5, the pusher 51 is an articulated pusher, comprising two lateral flaps 75 which revolve around an axis 77 on either side of the main body. During the material ejection phase, the articulated pusher 51 behaves as same way as a non-articulated pusher 51. When returning to position retracted from the pusher 51, the side flaps 75 have the possibility of being close in the direction of the vertical plane of symmetry of the bucket 3, which minimizes friction of the pusher 51 against the walls of the bucket 3, and promotes said retraction of the pusher 51.

Le déplacement du poussoir 51 dans la benne est commandé par un vérin horizontal hydraulique télescopique double effet 81.The movement of the pusher 51 in the bucket is controlled by a jack horizontal telescopic double effect 81.

Le fût 83 du vérin 81 est disposé sur le fond de la benne 3, à l'avant de celle-ci, vers le capot 15. Au fur et à mesure que se déploient ses éléments télescopiques 85 vers l'arrière de la benne 3, le vérin 81 pousse le poussoir 51 vers l'arrière de la benne 3, ce qui a pour effet d'éjecter les matériaux contenus dans la benne 3 entre le poussoir 51 et l'arrière de la benne 3. L'avantage d'une telle disposition du vérin 81 dans la benne 3 réside dans le fait que les contraintes de poids sur le poussoir 51 sont minimisées, et la répartition des charges sur le châssis 25 est améliorée. The barrel 83 of the jack 81 is disposed on the bottom of the bucket 3, at the front of this one, towards the hood 15. As its elements are deployed telescopic 85 towards the rear of the bucket 3, the jack 81 pushes the plunger 51 towards the rear of bucket 3, which has the effect of ejecting the materials contained in the bucket 3 between the pusher 51 and the rear of the bucket 3. The advantage of such an arrangement of the jack 81 in the bucket 3 lies in the fact that the weight constraints on the pusher 51 are minimized, and the load distribution on the chassis 25 is improved.

Les moyens de fixation du fût 83 du vérin 81 sur le fond de la benne 3 sont illustrés aux figures 4 et 5. Ils comprennent deux supports 87, deux traverses latérales intérieures 89, et deux chapes de fixation 93.The means for fixing the barrel 83 of the jack 81 to the bottom of the bucket 3 are illustrated in Figures 4 and 5. They include two supports 87, two internal lateral crosspieces 89, and two fixing yokes 93.

Sur l'exemple illustré aux figure qui représente le cas où le véhicule est un semi-remorque, les supports 87 ont sensiblement une forme de tour pyramidale. Ils sont fixés sur le fond de la benne 3, de part et d'autre du plan de symétrie verticale de celle-ci, et à l'avant de celle-ci.On the example illustrated in the figure which represents the case where the vehicle is a semi-trailer, the supports 87 have substantially the shape of a tower pyramid. They are fixed to the bottom of the bucket 3, on either side of the plane vertical symmetry thereof, and at the front thereof.

Les chapes de fixation 93 du vérin 81 sont fixées sur le sommet des deux supports 87, respectivement.The fixing yokes 93 of the jack 81 are fixed on the top of the two supports 87, respectively.

Chaque support 87 est renforcé par une traverse intérieure 89, fixée transversalement entre le haut de la face latérale orientée vers l'extérieur dudit support 87, et la paroi intérieure de la benne 3 au niveau où elle est renforcée par les second moyens longitudinaux de rigidification 13.Each support 87 is reinforced by an internal cross member 89, fixed transversely between the top of the outward-facing side face of said support 87, and the inner wall of the bucket 3 at the level where it is reinforced by the second longitudinal stiffening means 13.

Toutes les fixations qui viennent d'être mentionnées pour décrire la fixation du vérin 81, sont de préférence réalisées par soudage.All the fasteners which have just been mentioned to describe the fixing of the cylinder 81, are preferably made by welding.

Ce mode de fixation du vérin 81, et en particulier de la présence des deux traverses latérales intérieures 89, présente l'avantage de maintenir l'écartement des deux parois latérales de la benne 3. Il présente également l'avantage d'équilibrer le efforts de poussée du vérin 81 lors de la phase d'évacuation des matériaux, et donc de réduire les risques de déformation du châssis 25 et/ou de vrillage de la benne 3.This method of fixing the jack 81, and in particular the presence of the two internal lateral crosspieces 89, has the advantage of maintaining the spacing of the two side walls of the bucket 3. It also has the advantage of balancing the thrust forces of the jack 81 during the phase material evacuation, and therefore reduce the risk of deformation of the chassis 25 and / or twisting of the bucket 3.

Au cours de son déplacement de l'avant vers l'arrière ou de l'arrière vers l'avant de la benne 3, le poussoir 51 est guidé par des moyens de guidage 101, 103, 105, 107, 109, 111, 113, 115, 117, 119.During its movement from front to back or from back to the front of the bucket 3, the pusher 51 is guided by guide means 101, 103, 105, 107, 109, 111, 113, 115, 117, 119.

Selon le premier mode de réalisation illustré aux figures 1, 2, et 4, les moyens de guidage comprennent des premiers moyens de guidage 101, des deuxièmes moyens de guidage 103, 105 qui coopèrent avec les premiers moyens de guidage 101. Selon une variante optionnelle, mais préférée, les moyens de guidage comprennent en outre des troisièmes moyens de guidage 107, qui coopèrent également avec les premiers moyens de guidage 101. According to the first embodiment illustrated in Figures 1, 2, and 4, the guide means comprise first guide means 101, second guide means 103, 105 which cooperate with the first guide means 101. According to an optional variant, but preferred, the guide means further comprise third guide means 107, which also cooperate with the first guide means 101.

Les premiers moyens de guidage 101 comprennent des rainures longitudinales 101 de la face extérieure des bords supérieurs 7 de la benne 3. Ces rainures 101 présentent une forme de U, elles sont au nombre de deux et sont de préférence ménagées respectivement sur toute la longueur de chaque profilé longitudinal supérieur extérieur 11 de rigidification. De préférence, chaque rainure 101 est disposée à 20 cm au-dessous du bord libre de la benne 3.The first guide means 101 include grooves longitudinal 101 of the outer face of the upper edges 7 of the bucket 3. These grooves 101 have a U shape, they are among two and are preferably arranged respectively over the entire length of each external upper longitudinal section 11 of stiffening. Of preferably each groove 101 is arranged 20 cm below the edge free from bucket 3.

Les deuxièmes moyens de guidage 103, 105 comprennent des galets avant 103, et des galets arrières 105, solidaires du poussoir 51 et qui se déplacent longitudinalement dans les rainures 101. De préférence, le poussoir 51 est équipé d'un galet avant 103 de chaque côté et d'un galet arrière 105 de chaque côté.The second guide means 103, 105 comprise rollers front 103, and rear rollers 105, integral with the pusher 51 and which move longitudinally in the grooves 101. Preferably, the pusher 51 is equipped with a front roller 103 on each side and a roller rear 105 on each side.

Le guidage à quatre galets 103, 105 présente l'avantage d'améliorer la stabilité du poussoir 51 et de maintenir sa position verticale lors de son déplacement longitudinal. De préférence, l'écart entre les galets avant 103 et les galets arrière 105 est d'environ 0.80 à 1.20 m.The guide with four rollers 103, 105 has the advantage of improving the stability of the pusher 51 and to maintain its vertical position during its longitudinal displacement. Preferably, the distance between the front rollers 103 and the rear rollers 105 is approximately 0.80 to 1.20 m.

Les troisièmes moyens de guidage 107 comprennent des galets intermédiaires 107, solidaires du poussoir 51 qui se déplacent longitudinalement dans lesdites rainures 101. De préférence, les galets intermédiaires 107 sont au nombre de deux, et sont disposés de chaque côté, entre les galets avant 105 et les galets arrière 103, le long de la direction longitudinale de la benne 3.The third guide means 107 comprise rollers intermediaries 107, integral with the pusher 51 which move longitudinally in said grooves 101. Preferably, the rollers intermediaries 107 are two in number, and are arranged each side, between the front rollers 105 and the rear rollers 103, along the longitudinal direction of the bucket 3.

Les galets avant 103, les galets arrière 105, et les galets intermédiaires 107 sont respectivement reliés au poussoir 51 par des supports en forme de bras coudés 109.The front rollers 103, the rear rollers 105, and the intermediate rollers 107 are respectively connected to the pusher 51 by supports in the form of bent arms 109.

Les galets avant ou arrière 103, 105 parcourent les côtés du U formant les rainures 101, alors que les galets intermédiaires parcourent le fond du U formant les rainures 101. En d'autres termes, l'axe des deuxièmes moyens de guidage 103, 105 est horizontal au cours de leur déplacement dans les rainures 101, alors que l'axe des troisièmes moyens de guidage 107 est vertical au cours de leur déplacement dans les rainures 101. Cette orientation alternée des axes des galets 103, 105, 107 a pour avantage de réduire les risques de flambage de la partie supérieure de la benne 3, et de maintenir un écart sensiblement constant entre le support de joint 67 et le bord supérieur 7 de la benne 3, ce qui réduit encore les risques de retournement du joint d'étanchéité 65 lors du déplacement longitudinal du poussoir 51.The front or rear rollers 103, 105 run along the sides of the U forming the grooves 101, while the intermediate rollers run through the bottom of the U forming the grooves 101. In other words, the axis of the second guide means 103, 105 is horizontal during their displacement in the grooves 101, while the axis of the third guide means 107 is vertical during their movement in the grooves 101. This alternating orientation of the axes of the rollers 103, 105, 107 has the advantage of reducing the risk of part buckling upper part of the bucket 3, and maintain a substantially constant gap between the seal support 67 and the upper edge 7 of the bucket 3, which further reduces the risk of the seal 65 overturning when of the longitudinal movement of the pusher 51.

Selon le second mode de réalisation illustré à la figure 3, les moyens de guidage comprennent des premiers moyens de guidage 111, et des seconds moyens de guidage 113, 115, 117, 119 qui coopèrent avec les premiers moyens de guidage 111.According to the second embodiment illustrated in Figure 3, the means of guidance comprise first guidance means 111, and second guide means 113, 115, 117, 119 which cooperate with the first guide means 111.

Les premiers moyens de guidage 111 comprennent des rails longitudinaux 111 fixés sur toute la longueur de la face intérieure des bords supérieurs 7 de la benne 3. Ces rails 111 présentent de préférence une forme sensiblement parallélépipédique. Ils peuvent être renforcés par des pièces d'usure 125 visibles sur la figure 4. Ces pièces d'usure 125 peuvent être par exemple réalisées au moyen de deux plaques perpendiculaires soudées par points ou d'une forme en forme de L renversé, soudée par points.The first guide means 111 comprise rails longitudinal 111 fixed over the entire length of the inner face of the upper edges 7 of the bucket 3. These rails 111 have preferably a substantially parallelepiped shape. They can be reinforced by wearing parts 125 visible in FIG. 4. These parts wear 125 can for example be achieved by means of two perpendicular plates spot welded or shaped in shape de L inverted, spot welded.

Les seconds moyens de guidage 113, 115, 117, 119 comprennent des galets avant supérieurs 113, des galets avant inférieurs 115, des galets arrières supérieurs 117 et des galets arrières inférieurs 119, tous solidaires du poussoir 51 et qui se déplacent longitudinalement contre les faces supérieures et inférieures respectivement des rails 111. De préférence, le poussoir 51 est équipé d'un galet avant supérieur 113 de chaque côté, d'un galet avant inférieur 115 de chaque côté, d'un galet arrière supérieur 117 de chaque côté, et d'un galet amère inférieur 119 de chaque côté. Le guidage à huit galets 113, 115, 117, 119 présente l'avantage d'améliorer la stabilité du poussoir 51 et de maintenir sa position verticale lors de son déplacement longitudinal.The second guide means 113, 115, 117, 119 comprise upper front rollers 113, lower front rollers 115, rollers upper rear 117 and lower rear rollers 119, all integral with pusher 51 and which move longitudinally against the upper and lower faces of the rails 111. respectively preferably, the pusher 51 is equipped with an upper front roller 113 of each side with a lower front roller 115 on each side with a roller upper rear 117 on each side, and a lower bitter roller 119 of each side. The eight-roller guide 113, 115, 117, 119 has the advantage of improving the stability of the pusher 51 and of maintaining its position vertical during its longitudinal displacement.

Le second mode de réalisation qui vient d'être décrit est particulièrement bien adapté aux bennes 3 qui sont équipées d'une bâche destinée à assurer la conservation de la température des matériaux transportés. Sur le dessus de chaque bord supérieur 7 de la benne 3 est fixé un dispositif de guidage 121 de la bâche. Ce dispositif de guidage 121 se présente de préférence sous la forme d'une glissière en C dont les deux bras sont orientés vers le haut et présentent un rabat intérieur. The second embodiment which has just been described is particularly well suitable for skips 3 which are fitted with a tarpaulin intended to ensure the conservation of the temperature of the materials transported. On top of each upper edge 7 of the bucket 3 is fixed a guide device 121 tarpaulin. This guide device 121 is preferably provided under the shape of a C slide whose two arms are oriented upwards and have an interior flap.

Les matériaux et dimensions préférés des différents éléments qui ont été décrits ci-dessus sont les suivants :

  • benne 3 : acier résistant aux chocs et à l'abrasion, d'une dureté de 400 HB, ou bien acier inoxydable ou aluminium résistant à l'abrasion et à la corrosion, dont l'épaisseur est adaptée à la densité, l'abrasivité et la corrosivité des matériaux transportés.

  • joint 65 du poussoir 51 : acier à haute résistance à l'abrasion pour le transport de matériaux lourds et agressifs ; ou bien acier inoxydable avec molybdène et titane pour le transport de matériaux extrêmement corrosifs ; ou bien matière plastique de type PTFE résistant à des températures allant jusqu'à 250C ; ou bien polyamide ; ou bien téflon ; ou bien les dérivés des matériaux ci-dessus ; ou bien plaque de caoutchouc à deux, trois ou six plis de tissu croisé, avec trame polyamide et interface gommé à base de butyl résistant à des températures allant jusqu'à 220 °C.
The preferred materials and dimensions of the various elements which have been described above are the following:
  • bucket 3: steel resistant to impact and abrasion, with a hardness of 400 HB, or stainless steel or aluminum resistant to abrasion and corrosion, the thickness of which is adapted to the density, the abrasiveness and the corrosiveness of the materials transported.
  • chassis 25, false chassis: steel with high yield strength, or stainless steel bent in an angle or I, with a thickness of 4 to 5 mm, or aluminum with a thickness of 10 mm.
  • in the presence of a false chassis 45, it is preferred that the bucket 3 and / or the false chassis 45 are made of abrasion resistant aluminum rather than steel, which makes it possible to considerably reduce the dead weight of the vehicle. The reduction thus obtained can be of the order of two tonnes.

  • protective lining 57 of the pusher 51: steel with high elastic limit or stainless steel, with a thickness adapted to the nature of the materials transported; or else a rubber sheet with two, three or six plies of crossed fabric, with polyamide weft and gummed butyl-based interface resistant to temperatures up to 220 ° C; or plastic material of the PTFE type resistant to temperatures up to 250 ° C; or else polyamide; or Teflon; or the derivatives of the above materials; thickness from 5 to 15 mm.
  • seal 65 of pusher 51: steel with high abrasion resistance for transporting heavy and aggressive materials; or stainless steel with molybdenum and titanium for the transport of extremely corrosive materials; or plastic material of the PTFE type resistant to temperatures up to 250C; or else polyamide; or Teflon; or the derivatives of the above materials; or else a rubber sheet with two, three or six plies of crossed fabric, with polyamide weft and gummed butyl-based interface resistant to temperatures up to 220 ° C.

Un poussoir de forme semi-sphérique permet de maintenir les matériaux à éjecter dans l'axe de poussée du bouclier favorisant le glissement de la masse à l'intérieur de la benne 3 et empêche ainsi le débordement de ceux-ci par-dessus les bords supérieurs de la benne. La forme de la face de contact 53 du poussoir 51 ainsi réalisé permet d'alléger la structure arrière du bouclier, qui est opposée à la face de contact 53, permettant ainsi un gain de poids du poussoir 51, tout en conservant une bonne résistance mécanique aux efforts de poussée du vérin.A semi-spherical pusher keeps the materials at eject in the thrust axis of the shield favoring the sliding of the ground inside the bucket 3 and thus prevents them from overflowing over the top edges of the bucket. The shape of the face of contact 53 of pusher 51 thus produced makes it possible to lighten the rear structure of the shield, which is opposite to the contact face 53, thus allowing a gain of weight of pusher 51, while retaining good mechanical strength to the thrust forces of the jack.

L'invention n'est pas limitée aux modes de réalisation et variantes qui viennent d'être décrits, et toute adaptation et/ou modification à la portée de l'homme du métier peut être envisagée sans pour autant sortir du cadre de l'invention.The invention is not limited to the embodiments and variants which have just been described, and any adaptation and / or modification to the scope of the skilled person can be considered without departing from the scope of the invention.

En particulier, des modifications classiques peuvent être apportées au châssis qui a été décrit ci-dessus dans le cas où le véhicule est un semi-remorque, pour l'adapter aux autres types de véhicules concernés par l'invention : remorques, véhicules porteurs motorisés.In particular, classic modifications can be made to the chassis which has been described above in the case where the vehicle is a semi-trailer, to adapt it to other types of vehicles concerned by the invention: trailers, motorized carrier vehicles.

Par ailleurs, le déplacement du poussoir peut être commandé par deux vérins hydrauliques télescopiques montés en parallèle, alimentés par un système de répartition de débit et de pression. Cette adaptation est particulièrement adaptée aux bennes de dimensions importantes, typiquement de 80 à 100 mètres cubes.Furthermore, the movement of the pusher can be controlled by two telescopic hydraulic cylinders mounted in parallel, supplied by a flow and pressure distribution system. This adaptation is particularly suitable for large skips, typically 80 to 100 cubic meters.

D'une manière analogue, le poussoir peut être commandé par un ou deux vérins double effet déployant un ou plusieurs losanges extensibles dans le sens longitudinal de la benne. Cette adaptation est particulièrement adaptée aux bennes de faibles dimensions, typiquement ayant un volume de 5 à 15 mètres cubes. Elle a pour avantage de réduire l'espace perdu à l'avant de la benne quand le bouclier se trouve en position rétractée.Similarly, the pusher can be controlled by one or two double-acting cylinders deploying one or more expandable diamonds in the longitudinal direction of the bucket. This adaptation is particularly suitable to small skips, typically having a volume of 5 to 15 Cubic meters. It has the advantage of reducing the space lost at the front of the bucket when the shield is in the retracted position.

On peut également remplacer tout ou partie des galets de guidage par des patins de guidage remplissant la même fonction.It is also possible to replace all or part of the guide rollers with guide shoes performing the same function.
